    • There is described a method of creating a transparent window (W*) in a security, especially paper, substrate (1) for security printing applications, the method comprising the steps of (i) providing a security substrate (1), (ii) forming an opening (10*) into and through the security substrate (1), and (iii) filling the opening (10*) with transparent material (2) thereby forming the transparent window (W*). The filling of the opening (10*) with the transparent material (2) is carried out in a state where the opening (10*) is open on both sides of the security substrate (1) and extends through the security substrate (1), the filling of the opening (10*) including (10 the application of a first side (I) of the security substrate (1) against a supporting surface (21A) of a supporting member (20′, 21) in such a way as to block one side of the opening (10*), while the transparent material (2) is applied inside the opening (10*) from the other side (II) of the security substrate (1). Advantageously, the method further comprises the step of forming a field of lenses (L) on one side of the transparent window (W*), in particular by replicating the field of lenses (L) directly into the transparent material (2) filling the opening (10*). Also described is a suitable device designed to fill the opening (10*) with the transparent material (2).
    • 描述了在用于安全打印应用的安全特别是纸张基底(1)中形成透明窗口(W *)的方法,所述方法包括以下步骤:(i)提供安全基板(1),(ii) 在安全基板(1)中形成开口(10 *),并且(iii)用透明材料(2)填充开口(10 *),从而形成透明窗口(W *)。 开口(10 *)与透明材料(2)的填充在开口(10 *)在安全基板(1)的两侧开口并且穿过安全基板(1)延伸的状态下进行, (10 *)的填充包括(10)以这种方式将安全基板(1)的第一侧(I)施加到支撑构件(20',21)的支撑表面(21A)上 为了阻止开口(10 *)的一侧,同时透明材料(2)从安全基板(1)的另一侧(II)施加在开口(10 *)的内部,有利地,该方法还包括 特别是通过将透镜(L)直接复制到填充开口(10 *)的透明材料(2)中,在透明窗口(W *)的一侧上形成透镜(L)的场的步骤。 还描述了设计成用透明材料(2)填充开口(10 *)的合适的装置。
